Microsoft has detailed the “Menu” and “View” buttons on the new Xbox One controller, which replace the Xbox 360 controller’s “Start” and “Back” buttons.

The Menu button, located on the right, will pull up “context-specific menus which game and app developers can design to enhance the user experience,” Microsoft told IGN. It can be used by game developers to bring up in-game videos, show video playback options, or accessing commands on the console’s user interface.

The View button, located on the left, is a developer-programmed button that “will change views or provide more information in games and apps.” It can be used, for example, in a role-playing game to pull up a map, or in a first-person shooter to pull up a leaderboard.
